3 3 8 8 puzzle
Using the four numbers 3, 3, 8, and 8, and the usual four arithmetic operations (addition, subtraction, multiplication and division), can you make the number 24?
This looks a bit too easy (3 × 8 = 24), until I tell you that you have to use all four numbers - both 3s and both 8s. No silly tricks allowed - you can't use an 8 and a 3 to make 83, or raise numbers to powers or take square roots or factorials or anything else of that kind.
You can use fractions on the way, of course, but the final answer must be exactly 24. For example: 3 × 8 + (3/8) makes 24 and three-eighths, which is quite close, but no banana.
